The Nucleated RBCs Test, also known as the NRBC test, is an important diagnostic test used to detect immature red blood cells in your bloodstream. Normally, red blood cells (RBCs) mature in the bone marrow before entering the blood circulation. However, the presence of nucleated RBCs in a peripheral blood sample can indicate serious health conditions related to bone marrow stress, oxygen deficiency, or severe infections.
At Chughtai Lab, one of Pakistan’s most trusted and advanced diagnostic laboratories, the Nucleated RBCs Test is conducted with precision using modern hematology analyzers and expert review by qualified pathologists. This ensures highly accurate and reliable results for doctors to diagnose underlying conditions.
If your doctor has recommended a Nucleated RBCs Test, it’s essential to understand what the test measures, how it’s done, and what your results mean. This guide explains everything you need to know including the Chughtai Lab Nucleated RBCs Test price (Rs. 350), the preparation process, report details, and booking information.
What is a Nucleated RBCs Test?
The Nucleated RBCs (NRBCs) Test measures the number of immature red blood cells present in your bloodstream. Normally, mature red blood cells do not have a nucleus, as they lose it during the final stage of development in the bone marrow. However, when the body is under stress or facing certain health conditions, the bone marrow may release immature red blood cells (which still contain a nucleus) into the circulation.
This test is typically performed as part of a Complete Blood Count (CBC) or during detailed blood analysis when a doctor suspects abnormalities in blood cell production or bone marrow function.
Doctors may recommend this test for:
- Evaluating bone marrow response after bleeding or infection
- Diagnosing anemia or blood loss
- Assessing oxygen deprivation or hypoxia
- Monitoring leukemia or other bone marrow diseases
- Tracking treatment response in critical care patients
Why is the Nucleated RBCs Test Important?
The Nucleated RBCs Test plays a critical role in identifying conditions that disrupt normal blood cell production. The presence of nucleated RBCs in the peripheral blood can be a sign of:
- Severe anemia
- Bone marrow disorders (like myelodysplastic syndrome)
- Hypoxia (low oxygen levels)
- Sepsis or severe infection
- Hemolytic anemia
- Leukemia or blood cancer
For newborns, the presence of NRBCs can be normal during the first few days of life, as their bone marrow is still adjusting. However, in adults and older children, even a small count of nucleated RBCs is considered abnormal and needs medical evaluation.
This test helps doctors understand how your body is responding to stress, infection, or oxygen deficiency making it a valuable tool in medical diagnostics.
When Should You Get a Nucleated RBCs Test?
Your doctor may recommend the Nucleated RBCs Test if you show symptoms that indicate issues with blood or bone marrow function, such as:
- Persistent fatigue or weakness
- Unexplained anemia
- Shortness of breath
- Unusual bleeding or bruising
- Recurrent infections
- Signs of hypoxia (oxygen deprivation)
- Following chemotherapy or radiation therapy
Additionally, doctors may advise this test for patients in intensive care units (ICUs), as NRBC levels can help assess the severity of illness and predict recovery outcomes.
How to Prepare for the Nucleated RBCs Test?
The Nucleated RBCs Test generally requires no special preparation. However, for the most accurate results, here are some guidelines to follow:
- No fasting needed: You can eat and drink normally before the test unless your doctor advises otherwise.
- Medication disclosure: Inform your healthcare provider about any medications or supplements you are taking, as certain drugs may influence blood results.
- Stay hydrated: Drink sufficient water before your test to make the blood draw easier.
- Avoid stress: Try to relax before sample collection to prevent stress-induced changes in blood composition.
If the NRBC test is part of a comprehensive blood test like a CBC or bone marrow evaluation, additional preparation instructions may apply, which your doctor or Chughtai Lab staff will guide you through.

At Chughtai Lab, the Nucleated RBCs Test is performed by experienced phlebotomists using advanced automated blood analyzers to ensure high accuracy. Here’s what to expect:
- Sample Collection: A small blood sample is taken from a vein in your arm using a sterile needle. The process takes only a few minutes.
- Sample Analysis: The blood sample is analyzed using state-of-the-art hematology machines that can detect even minute quantities of nucleated red blood cells.
- Quality Control: Every test undergoes a review by expert laboratory scientists and pathologists to confirm accuracy.
- Report Generation: The final Chughtai Lab Nucleated RBCs Test report includes detailed results, including NRBC count, WBC count, and other relevant blood parameters.
Chughtai Lab ensures that every test is handled with utmost care, accuracy, and confidentiality, giving you reliable results within the shortest possible turnaround time.
Nucleated RBCs Test Report & Normal Values
Normal Range Table
| Parameter | Normal Range | Unit |
| Nucleated RBCs (Adults) | 0 | per 100 WBCs |
| Nucleated RBCs (Newborns) | 0-10 | per 100 WBCs |
In healthy adults, NRBCs should not be present in the peripheral blood. The detection of NRBCs indicates an abnormal condition or bone marrow stress. In newborns, however, a small number of NRBCs is normal immediately after birth.
Report Interpretation:
- NRBC = 0: Normal finding, indicating healthy blood formation.
- NRBC > 0: Suggests increased bone marrow activity due to stress, hypoxia, or disease.
Your doctor will interpret your results in combination with other tests like the CBC, reticulocyte count, and peripheral blood smear for accurate diagnosis.
Understanding Abnormal Results
Abnormal Nucleated RBCs Test results can have several possible causes:
Common Causes of Elevated NRBCs:
- Severe anemia especially hemolytic or megaloblastic types.
- Bone marrow damage or cancer conditions like leukemia or myelofibrosis.
- Hypoxia chronic oxygen deficiency due to lung or heart conditions.
- Acute blood loss the bone marrow releases immature cells to compensate.
- Sepsis or systemic infection stimulates excess blood cell production.
- Post-surgery or trauma due to stress and blood loss recovery.
High NRBC counts are often a red flag for doctors to conduct further investigations.
Important: Never self-diagnose based on test results. Always consult a certified healthcare provider to interpret the findings and determine the right treatment or follow-up tests.
How to Support Healthy Blood Formation Naturally
While abnormal NRBC levels require medical assessment, maintaining healthy red blood cell production can be supported by good lifestyle habits:
- Eat iron-rich foods like spinach, red meat, lentils, and beans.
- Consume Vitamin B12 and folate from eggs, dairy, and green vegetables.
- Stay hydrated and avoid excessive caffeine or alcohol.
- Exercise regularly to promote oxygen circulation.
- Avoid smoking, as it can damage red blood cells and bone marrow function.
These habits can contribute to maintaining balanced blood health and reducing the risk of anemia or related disorders.
